Wow, this game moves fast.
I don't have much to say about LittleGumball, because I have yet to see anything scream scum, but I certainly don't feel comfortable leaning her town. From what I remember with LG, she always manages to be super active and post good thoughts even while scum. I never paid too much attention to her meta, so I don't think I'm going to rely on that when it comes to reading her or any of the "all-stars."
As for jester, I think we should wait until after the night before we should be too worried if one even exists. I can't remember seeing a game with a jester on ZD and would be surprised to see one. Regardless, if we have a third party role, then I can't imagine we have very many. If a serial killer is present, then I would bet that thats the only third party. Maybe a survivor as well, but I've only seen that a few times.
I also don't understand how we're already talking about who the entirety of the scum team is. We have nothing at this point to credibly go off of, and I can't imagine that the whole scumteam would have even noticeably interacted with one another this early in the game. Especially when nobody has been close to being lynched.
